- To demonstrate the superiority of glimepiride and metformin free combination in comparison to glimepiride or metformin alone in terms of Hb1Ac reduction during a 24-week treatment period in patients with type 2 diabetes mellitus.

Secondary Objectives:

- To assess the effects of the free combination of glimepiride and metformin in comparison to glimepiride or metformin alone on:

Percentage of patients reaching HbA1c < 7%

Percentage of patients reaching HbA1c < 6.5%

Fasting Plasma Glucose (FPG)

Safety and tolerability

Detailed Description

The study duration for each patient is approximately 27 weeks with 3 periods: 2-week screening period followed by 24-week treatment period where patient is assigned to one of the three arms according to randomization, and 3 days follow-up period with a last call phone visit.

24-week treatment period: After randomization, starting dose will be of 2 mg /day or 1 mg/day of glimepiride if Fasting Plasma Glucose (FPG) at baseline < 180 mg/dL (10 mmol/L) taken once in the morning before breakfast. The treatment's dose will be increased every 2 weeks up to the maximum tolerated dose of 4 mg, and adjusted throughout the 24-week treatment period according to fasting Self Monitored Plasma Glucose (SMPG) values in the objective to obtain fasting SMPG values ≤ 130mg/dL (7.2mmol/L) and > 70 mg/dL (3.9mmol/L) without symptomatic hypoglycemia.

Intervention: Drug: GLIMEPIRIDE

Experimental: ARM 2: metformin alone

24-week treatment period: After randomization, starting dose will be of 500 mg of metformin twice a day during or after meals. The treatment's dose will be increased every 2 weeks up to the maximum tolerated dose of 2000 mg, and adjusted throughout the 24-week treatment period according to fasting SMPG values in the objective to obtain fasting SMPG values ≤ 130mg/dL (7.2mmol/L) and > 70 mg/dL (3.9mmol/L) without symptomatic hypoglycemia.

Intervention: Drug: METFORMIN

Experimental: ARM3: Glimepiride/metformin free combination

24-week treatment period: After randomization, starting dose will be of 2 mg /day or 1 mg/day of glimepiride if FPG at baseline < 180 mg/dL (10 mmol/L) taken once in the morning and 500 mg of metformin twice a day taken during or after meals. The treatment's dose will be increased every 2 weeks up to the maximum tolerated dose of 4 mg of glimepiride and 2000 mg of metformin, and adjusted throughout the 24-week treatment period according to fasting SMPG values in the objective to obtain values ≤.
